Yesterday I wanted to try the new InDesign CC (I have the Creative Suite CS for students) and after installing it, my CS3 (legally bought years ago) suddenly stopped working.
The app (for example Photoshop CS3) opens. It shows the "license agreement". Then, as I click "Agree", the windows closes. And that's it. The same goes for all other CS3 apps. Clicking "Agree" just closes the app.
I use Windows 10, English version. The CS3 bundle is in Czech.
Please help, this is not good.
You have to clean out the whole activation system stuff from CC and reinstall your CS3.
